1. Pan form

According to the record and the corresponding so-called MD data layout of reproducing part of the video camera of present embodiment, the data recording of this form is recorded to mini-disk (magneto-optic disk) and/or from mini-disk.Up to now, MD-data 1 and MD-data 2 these 2 kinds of MD data layouts have been developed.According to the camera record and the data of reproducing corresponding to MD-data 2 forms of present embodiment, these MD-data 2 forms are than MD-data 1 format record density height.At first, the form to the CD of MD-data 2 forms is described.

Fig. 1 and 2 schematically illustrates the example corresponding to the track structure of the CD of MD-data 2 forms.Fig. 2 A and 2B be respectively part that demonstration irised out by the empty frame A of Fig. 1 amplification sectional view and the planimetric map that has amplified.

As shown in these figures, at the pre-groove (groove) that forms 2 types in the surface of CD.First kind of groove is groove (wobbled groove) WG of swing, and its groove is swung.Second kind of groove is the groove NWG that does not have swing, and its groove is not have swing.The groove NWG of the groove WG of swing and nothing swing forms with double screw shape on CD, makes between form a platform (land) LD.

In MD-data 2 forms, this platform LD is used as track record (data are recorded in top).Because the groove WG of swing and the groove NWG that does not have a swing are preformed by this way, 2 track TrA and TrB independently form with double screw shape as track record.

On track TrA, the groove NWG of the groove WG of swing and nothing swing forms in the outward flange side of dish and the inward flange side of CD respectively.

On the contrary, on track TrB, the groove NWG of the groove WG of swing and nothing swing forms in the inward flange side of dish and the outward flange side of CD respectively.

In other words, on track TrA, swing only is formed in the outward flange side of dish.On the contrary, on track TrB, swing only forms in the inward flange side of dish.

In this case, track space is the distance between the center of adjacent orbit TrA and track TrB.Shown in Fig. 2 B, this track space is 0.95 μ m.

Swing forms on groove, as corresponding to the groove WG of the physical address on the dish by the swing of FM modulation and bi-phase modulated encoded signals.Therefore, by the information of demodulation, can extract the physical address on the placing from the groove reproduction of swing.

Address information as the groove WG that swings is public to track TrA and track TrB.In other words, track TrA that forms in the inward flange side of groove WG and the outward flange side of swing and the track TrB address information of sharing the swing of the groove WG that distributes to swing.

This addressing system is also referred to as the interleaved addressing system.Use this interleaved addressing system, can reduce track space, can suppress crosstalking between the adjacent swing again.On groove, form the addressing system of swinging and also be known as ADIP (address in the pre-groove) system as the address.

The track TrA of expression shared address information and which the current tracked identification among the track TrB are carried out in the following manner.

For example, use 3 beam system, when main beam was followed the tracks of track (platform Ld), other 2 side beams were followed the tracks of the groove in these track both sides.

As the example of a reality, Fig. 2 B has shown that main spot SPM is following the tracks of the state of track TrA.In this case, follow the tracks of no wobble groove NWG at the side spots SPs1 of inward flange side, and the side spots SPs2 of its outer edges side follows the tracks of the groove NWG of swing.

On the other hand, following the tracks of at main spot SPm under the situation of track TrB, side spots SPs1 follows the tracks of the groove WG of swing, and side spots SPs2 follows the tracks of the groove NWG (this situation is not shown) that does not have swing.

Therefore, depend on that main spot SPm follows the tracks of track TrA or follows the tracks of track TrB, the groove that side spots SPs1 and SPs2 follow the tracks of is at the groove WG of swing and do not have between the groove NWG of swing and change.

The waveform of the detectable signal that is obtained by photo-detector according to the reflection of side spots SPs1 and SPs2 depends on that side spots SPs1 and SPs2 following the tracks of is that among the groove WG of swing and the groove NWG that does not have swing which changes.Therefore, which among side spots SPs1 and the SPs2 to follow the tracks of the groove WG groove NWG of swing (or do not have) of swing, can determine main beam is being followed the tracks of which track (track TrA or track TrB) according to.

Fig. 3 is the synoptic diagram that the important technological parameters of above-mentioned MD-data 2 forms of expression and MD-data 1 form compares.

In MD-data 1 form, track space is 1.6 μ m; The length in hole is 0.59 μ m/ position; Wavelength of Laser λ=780nm; The aperture NA=0.45 of shaven head.

The system of distance of MD-data 1 form is the groove register system.In other words, in MD-data 1 form, groove is used as record and reproduces the track of data.

Groove (track) forms as the addressing system in MD-data 1 form with spirality.Form as address information rolling to each side of groove.In other words, the groove of swing is used as the addressing system of MD-data 1 form.

In MD-data 1 form, EFM (8-14 conversion) system is used as the record data modulating system.ACIRC (senior staggered Reed-Solomon sign indicating number) is used as error correction system.The convolution type is used as the data interlace system.Therefore, in MD-data 1 form, data redundancy is 46.3%.

In MD-data 1 form, CLV (constant linear velocity) is used as the drive system of dish.The linear velocity of CLV is 1.2m/sec.Under the recoding/reproduction pattern, the data rate of standard is 133kB/sec (kilobytes/second).Recording capacity is 140MB (megabyte).

On the other hand, in MD-data 2 forms according to video camera of the present invention, track space is 0.95 μ m, and the length in hole is 0.39 μ m/ position, and it is littler than MD-data 1 form.In addition, for realizing the length in above-mentioned hole, Wavelength of Laser λ=650nm; The aperture rate NA=0.45 of shaven head makes hot spot narrow down at the diameter of focal position, and the wave band of photosystem broadens.

Described as reference Fig. 1, Fig. 2 A and Fig. 2 B, the platform register system is used as register system.The interleaved addressing system is used as addressing system.(RLL: limited travel length) system is used as the record data modulating system to the RLL (1.7) of suitable high density recording.The RS-PC system is used as interleaving systems.The piece finishing type is used as the release of an interleave system.Therefore, in MD-data 2 forms, the redundancy of data is lowered to 19.7%.

In MD-data 2 forms, CLV (constant linear velocity) is used as the drive system of dish.The linear velocity of CLV is 2.0m/sec.Under the recoding/reproduction pattern, the data rate of standard is 589kB/sec.Recording capacity is 650MB.In MD-data 2 forms, can realize than in the high about 4 times high density recording of MD-data 1 form.

When moving image is recorded with MD-data 2 forms, if motion image data with MPEG2 form compressed encoding, though depend on the bit rate of coded data writing time, can write down 15 to 17 minutes moving image.Have only when the recorde audio signal data,, can write down about 10 hours voice data if it is with the form compressed encoding of ATRAC (adaptive transformation acoustic coding) 2.

Fig. 9 represents the notion according to the example of the data power of the CD 51 of present embodiment.The physical format of the CD 51 shown in Fig. 9 identical with shown in Fig. 2 A and the 2B.

On CD 51, PTOC and RTOC are formed as power information.PTOC comprises the predetermined electric power information about the hole.The content of PTOC can not be rewritten.

RTOC comprises the necessary basic information of data that writes down on the management CD.

In this example, RTOC comprises and be used for managing track (may be the synonym of file) and file (folder) information of (being used to manage the structure of the conduct group of track) under record and reproduction mode.

Corresponding to the data that write down on CD with such as the result who wipes the editing and processing the processing to track (file) or file, the content of RTOC often is rewritten.

User's data are managed as being placed on a volume file under the root folder.In the present embodiment, volume (volume) is defined as one group of complete user's data.Define a dish and only comprise a volume.Except by PTOC and the RTOC information of managing be included in this volume data be placed in the volume file, other file and track in.

Volume index track (VTR) with predetermined size (for example, 12 bunches) is placed in the volume file.

PTOC and RTOC are defined as main management information.On the other hand, the volume index track is defined as sub-management information area.The volume index track has a table, and this table comprises characteristic, file and auxiliary data and the title thereof of track (file), and the information that is used to manage the integrated data that constitutes track.

After the volume index track, the micro track can selectedly be placed on the CD 51.At the micro track in RTOC district first bunch of include file at least.Along with the quantity change of file is big, the miniature image data volume increases.When the miniature image data volume surpassed the recording capacity of the micro track in the RTOC district, the data that are not recorded in the micro track were recorded recorded data district (will be described below) in addition.In this case, upward managed at volume index track (or RTOC) at the micro track in recorded data district.

After the micro track in the RTOC district, be used for the district of literal and be used for can be by the optional dish 51 that is placed on as the district of the view data of auxiliary data.

When lteral data amount and image data amount surpassed the recording capacity that RTOC goes, the lteral data and the view data that are not recorded in the RTOC district can be recorded the recorded data district by this way in addition, and promptly it is managed on volume index track (or RTOC).

The address location of recorded data district from representing by recorded data district start address W.The recorded data district comprises the AV data, i.e. track (file) data.In addition, the recorded data district comprises miniature image data and auxiliary data.

After the recorded data district, form leading-out zone to outermost edge from the address location of representing by leading-out zone start address L.

The division in above-mentioned district is specially track TrA to be carried out.But, from Figure 10, can know and find out that the division in above-mentioned district also is applicable to track TrB.But at present, the RTOC district that is used for track TrB is not defined as yet.In other words, the RTOC district in fact only is used for track TrA.

It should be noted that the just individual example of structure with reference to the CD of Fig. 9 and Figure 10 description.In other words, the physical location in each district on the CD can change corresponding to the practical operation situation of video camera.In addition, data structure can be changed.

6. ED position change editing operation

6-1. operate 1 general introduction (under the situation of camera mode)

In video camera,, on CD, be that data division after the ad-hoc location of last track of data of unit management can be wiped free of with file (track) as a kind of simple editting function according to present embodiment.This operation is called as the editing operation of ED position change.

To the camera mode track of the video data (or Still image data) that is included in moving image captured under the camera mode and be included in the interview track that the conduct of writing down under the interview pattern is recorded in the sound/Still image data of the file on the CD, carry out the data end position and change editting function.

In the editing operation of ED position change, main rotating disc 300 is in camera mode position or interview mode position.In addition, when data can be recorded to camera mode track or interview track, the editing operation of ED position change can be performed.

At first, with reference to Figure 11 A to 11D, to being under the situation of camera mode position at main rotating disc 300, the processing and the operation that change the ED position are described.

As mentioned above, under camera mode, when release key 301 or shooting key 304 when being operated, the shooting key enters the video data of moving image or the pattern that rest image can be recorded.

According to present embodiment, under camera mode, broadcast/Pause key 308 can be operated.When broadcast/Pause key 308 is operated, selected the track of last track (having last orbit number) on being recorded in dish.

Because selected camera mode, so it is selected to be recorded in the last track of the camera mode track on the CD under camera mode.In other words, the track that writes down or produce at the interview pattern track that writes down under the interview pattern with under the pattern except that camera mode does not have selected.

Selected in the above described manner last camera mode track is reproduced.

In other words, shown in Figure 11 A, data are reproduced by the reference position A1 from last track.The image of the last track of Zai Xianing is presented on the display panel 67 by this way.The user can see the image of last track on display panel 67.At this moment, reproduced synchronously by the sound of microphone record with moving image and moving image.

In Figure 11 A, in the end the district after the address A3 behind the end address A2 of track is a dead zone.

By when last track reproduces, the user can suspend the reproduction operation in the position of his desirable last track in data.In order to carry out pausing operation, the user can operate broadcast/Pause key 308 once more.The user selects to suspend the position as his desirable ED position.In other words, suspend the reference position that the corresponding user in position wishes the data division wiped.

The position of the reproduction of being carried out by the user that pausing operation suspended is represented by position Pst1 shown among Figure 11 A.

When the user had carried out pausing operation, the image that shows before pausing operation was presented on the display panel 67 as rest image.In other words, the data image corresponding to the pausing operation Pst1 shown in Figure 11 A is presented on the display panel 67 as rest image.Under this state, when fine motion dial 303 is rotated, begin sense of rotation corresponding to fine motion dial 303 from the time-out position Pst1 shown in Figure 11 A, image is shown frame by frame.

When in data with suspend when considering the frame-for-frame playback operation in the relation between the position, shown in Figure 11 B, be changed corresponding to the initial time-out position Pst1 that suspends the position and be time-out position Pst2 corresponding to the sense of rotation of fine motion dial 303.

When watching image on display screen, the user changes and suspends position Pst1.Finally, the user can adjust to the ED position of his desired change meticulously.

By this way, suppose that the user has adjusted the time-out position meticulously and final the appointment suspended position Pst2 (in this embodiment, suspend position Pst2 at last and can become Pst1).After this, the user operates erase key 302.

When the user operated this erase key, the shooting key reproduced data the district of the end position address A2 from final time-out position Pst2 to the last track shown in Figure 11 C, make the user can check this ED position of his desired change.At this moment, the image/sound of shooting key output reproduction.Data in this district are the data divisions that are wiped free of.Data in this district are repeatedly reproduced.

The user watches the image of repetition on display panel 67.Therefore, the user can check his the desired image of wiping.

At this moment, make the user can determine the dialog box (dialog) of erase operation or cancellation erase operation to be presented on the display screen.The user is by rotation and push this dialog boxes execution decision operation of fine motion dial 303 uses.This dialog box shows 2 buttons, i.e. cancel button and wipe decision button.The user by rotation fine motion dial 303 can select 2 buttons one of them.If main points touch the button (carrying out the decision operation), the user presses fine motion dial 303.

When the user wants to cancel the reference position (that is, finally suspending position Pst2) of specifying the data division of wiping, he uses this dialog box to carry out the cancellation operation.Therefore, the reference position of shooting key cancellation data designated part and enter record holding state under the normal shooting key pattern.

On the other hand, during the reference position of the data designated part that has determined to wipe as the user, he uses this dialog box to carry out erase operation.

During the reference position of the data designated part that has determined to wipe as the user, the data field of last track becomes end position A2-1 as shown in Figure 11 D from start address A1.In other words, the end position of last track becomes address A2-1 from the address A2 shown in Figure 11 A and the 11C, uses the final address of suspending position Pst2 appointment to be right after after the A2-1 of address, and the address A2 shown in Figure 11 D is right after after the final time-out position Pst2.

At this moment, for example management information is changed, and makes the end address A2-1 that changes become the end address of last track.According to present embodiment, the content of RTOC and volume index track are updated at least.When the text file corresponding to last track is recorded on the CD and the content of text file should change corresponding to the variation of FA final address the time, text file also is updated.

As mentioned above, after the end address of data was changed, shown in Figure 11 D, the district after following the address A2-2 of address A2-1 closely was used as the dead zone management.Therefore, when video camera reproduced last track, video camera stopped the reproduction of last track at end address A2-1.

On dish, the data of original last track are left on from the address A2-2 shown in Figure 11 D in the district of A2.But this district is used as the dead zone management.

After the end address of data changes by this way, when track under camera mode during by new record, before the end address of data changed, last track was used as the track track management following closely by new record.When 2 tracks during by successively reproducing, the district from start address A1 to end address A2-1 is used as by last track track following closely reproduces.Therefore, the last track of new record is used as last track reproduction.

In other words, according to present embodiment, when ED position (end address) when being changed, under camera mode, in the end the district after any desirable Data Position of track is wiped free of.After this, new track is recorded as last track.At this moment, when the user suitably selects the Data Position (suspend position Pst1) of last track, he like a cork carries out image connect and editing operation.

During data division after the user wipes the time-out position Pst1 of track in the end, consider user's friendly and prevent that data from being wiped by mistake, except that other frame-for-frame playback operation and cancellation determined/wipe the decision operation, he can operate these shirtsleeve operations by reproduction pausing operation and erase key and wipe these data like a cork.

In this case, the ED position of each track is represented in the ED position.But, in this case, because the target track of reformed ED position is last track, the end position of the ED position person's of being to use data (it is limited to the data of camera mode track).

In addition, in this case, the district from the time-out position Pst2 of appointment to end address A2 is the target that will wipe.Perhaps, suspending position Pst2 can be designated as end position A2-1.

Under the situation of image, with the frame unit appointment because suspend the position, end position A2-1 is the end position by the image of the former frame of the image that suspends position Pst2 appointment.

6-2. operate 2 general introduction (under the situation of interview pattern)

Next, with reference to Figure 12 A to 12D, will processing and the operation under the reformed situation in ED position under the interview pattern be described.As hereinafter described, the processing under interview (interview) pattern under the reformed situation in ED position and operation are with described identical under camera mode with reference to Figure 11 A to 11D.

Under the interview pattern, when user's operation note key 313, the sound of collecting from microphone 202 is recorded.When the sound of microphone was recorded, when the user operated shooting key 304 (or release key 301), static image was recorded.When data under the reproduction/edit pattern from the interview track when reproduced, video camera reproduces sound and shows rest image by its sequential that is recorded.

When the user operates broadcast/Pause key 308 under the interview pattern, selected the track of last track on being recorded in CD.

At this moment, under the interview pattern, as last track, last track is selected from the interview pattern track that is write down under the interview pattern.

Shown in Figure 12 A, the data of interviewing track at last are reproduced.At this moment, the sound of the interview track of reproduction is output.In addition, rest image is shown by the sequential that it is recorded.For example, under the situation shown in Figure 12 A, last interview track comprises rest image 1 and rest image 2.After the data of last interview track are reproduced, show rest image 1 at recovery time t1.Show rest image 2 at recovery time t2.In this case, rest image 2 is shown continuously up to this track end.

Similarly, in Figure 12 A, the district after following the address A3 of end address A2 closely is a dead zone.

In this case, the user in the end he carries out pausing operation in desirable position on the track.When the user when the time-out position Pst1 shown in Figure 12 A carries out pausing operation, the output of the sound of reproduction is suspended.In addition, when showing rest image before pausing operation is carried out, rest image is repeated to show.Under the situation shown in Figure 12 A, when carrying out pausing operation, because rest image 2 is shown, rest image 2 is displayed on the display panel 67.

Under the interview pattern, when fine motion dial 303 was rotated, to each phoneme, sound was also reproduced.In other words, at the time-out position Pst1 shown in Figure 12 B, the address of voice data is changed.

When time-out position Pst1 was changed by operating (not shown) by the phoneme audio reproduction, if rest image is changed corresponding to suspending position Pst1, the rest image of change was shown.

The user adjusted suspend position Pst and final specify suspend position Pst2 after, when the user operates erase key 302, shown in Figure 12 C, video camera is from final time-out position Pst2 repetition voice data the district of the end address A2 of track to the end.When this district comprised rest image, video camera was also exported this rest image.In the example shown in Figure 12 C, except reproducing this sound, video camera shows rest image 2.In this case, the data in the zone of this repetition are the data divisions that are wiped free of.

Dialog box is presented on the display screen.This dialog box shows 2 buttons, i.e. cancel button and wipe decision button.The user is by rotating and pressing fine motion dial 303 and operate cancel button and wipe decision button.

When the user operated cancel button, the zone of video camera cancellation appointment also entered record holding state under the normal camera mode.

On the other hand, when decision button was wiped in user's operation, shown in Figure 12 D, the data field of last track was changed to the zone from reference position A1 to end position A2-1.

After this, for example management information (RTOC, volume index track, text file etc.) is updated the end address that makes the end address A2-1 that changes become last track.

Therefore, shown in Figure 12 D, the zone after following the address A2-2 of address A2-1 closely is used as the dead zone management.When the data of last track are reproduced, reproduce sound from address A1.After this, show rest image 1 from recovery time t1 to recovery time t2.At end address A2-1, the reproduction of rest image 2 is done.

6-3. handle

Next, with reference to process flow diagram shown in Figure 13 the processing of finishing the operation of ED position change is described.

In this embodiment, will the processing (seeing Figure 11 A to 11D) under describing at video camera be described.In the processing shown in Figure 13, Video Controller 38 uses as master controller.When in case of necessity, execution control and treatment separately such as data processing/system, control circuit 31, camera control unit 25, driver controller 46 are to finish the processing that the data end position is changed operation.In the following description, each controller is called controller simply.

At step S101, camera mode is designated.At step S102, controller is determined the user, and whether executive logging is operated.When the result who determines at step S102 is that flow process does not advance to step S103.At step S103, controller determines whether the user carries out the reproduction operation.When the result who determines at step S103 whether, flow process advances to step S101.Controller waits for that at step S102 or step 103 state of recording operation or reproduction operation is the holding state under the camera mode.

When the result who determines at step S102 for being (be user operated release key 301 record moving images or take key 304 and write down rest images), flow process advances to step S114.At step S114, controller is carried out control and treatment so that rest image is recorded on the dish as motion image data or Still image data.At step S115, controller determines whether recording operation is finished.As the result who determines at step S115 is to deny (that is, unless recording operation is finished), and flow process is returned step S114.Therefore, recording operation is proceeded.

(at step S115) controller determines whether that the space of coiling uses up, and rest image has been recorded or has write down shut-down operation and has been performed.When the result who determines at step S115 for being that flow process advances to step S116.At step S116, controller is carried out control and treatment to finish recording operation (comprising the operation of renewal corresponding to record result's management information).After this, flow process is returned step S101.In other words, controller enters holding state.

When the result who determines at step S103 for being (be user used broadcasts/Pause key 308 to carry out reproduction operate), flow process advances to step S104.At step S104, controller begins to reproduce the last track as the camera mode track.Controller has detected pausing operation to last track repetition operation up to this controller.At this moment, controller is also carried out control to show that on display panel 67 moving image is as the data of reproducing.

When in the determined result of step S105 for being (being that the user operates broadcast/Pause key 308 once more), flow process advances to step S106.

At step S106, controller implements to suspend the control and treatment of reproducing operation.At this moment, the reproduction of data operation is parked in and suspends position Pst1.In addition, controller is carried out and is shown that controlling the data that make corresponding to the address of suspending position Pst is presented on the display panel 67 as rest image.

At step S107, controller determines whether the user has rotated fine motion dial 303 and carried out the frame-for-frame playback operation.When the result who determines at step S107 is that flow process does not advance to step S109.At step S109, controller determines whether the user has operated erase key 302.When the result who determines at step S109 is that flow process does not advance to step S106.At step S106, controller is suspending position Pst1 maintenance halted state.

When the result who determines at step S107 for being that flow process advances to step S108.At step S108, controller is implemented control and treatment to the operation of the reconstruction of image frame by frame corresponding to the selection operation of fine motion dial.In other words, described as reference Figure 11 B, controller changes and specifies and suspend position Pst1, and will show as image in the data with the corresponding address place, time-out position that changes.As the result who determines at step S109 is to deny (promptly flow process turns back to step S106 after step S108), is shown in the view data with the Pst1 corresponding address place, time-out position that changes by the control and treatment to reconstruction of image operation frame by frame.

When the result who determines at step S109 when being (being that erase key 302 is operated), flow process advances to step S110.

At step S101, described as reference Figure 11 C, controller is carried out the rail portion that control and treatment begins from the address after final appointed time-out position Pst1 with repetition.At this moment, the image as the data of reproducing is displayed on the display panel 67.As mentioned above, controller is carried out the dialog box that control and treatment comprises cancel button and wipes button with demonstration.Perhaps, controller can be carried out control and treatment repeatedly to be reproduced in the data of suspending position Pst1 adjustment before.

At step S111, controller determines whether the user has operated cancel button (i.e. cancellation decision operation) on dialog box.

When the result who determines at step S111 for being that flow process turns back to step S101.At step S111, controller returns to the holding state under the camera mode.On the other hand, when the result who determines at step S111 for not, flow process advances to step S112.

At step S112, whether controller determines the user, and (with the decision button on the dialog box) carried out and wiped decision operation.When the result who determines at step S112 is that flow process does not turn back to step S110.At step S110, controller is to the operation of the orbital data repetition after suspending position Pst1.On the other hand, when the result who determines at step S112 when being, flow process advances to step S113.At step S113, controller is carried out and is handled to wipe the orbital data part after suspending position Pst1.In other words, controller more the content of the management information of new subscription make the zone of data division of the last track after suspending position Pst1 be used as the dead zone to manage.At this moment, controller is carried out the processing of the message that indicator gauge registration certificate has been wiped free of on display panel 67.

After step S101 controller was finished processing, flow process turned back to step S101.At step S101, controller enters the holding state under the camera mode.

The processing to the operation of the ED position change under camera mode as shown in figure 12 can be applied to the processing under the camera mode shown in Figure 13.But in this case, at step S101, the interview pattern is designated.At step S104, controller reproduces last track as interview pattern track.At this moment, as reproducing operation, controller is implemented the reproducing control processing makes the rest image of sound/interview pattern track be output.

At step S102, controller is determined the user, and whether operational example is as record key 313.When the result who determines at step S102 for being that flow process advances to step S114.At step S114, controller is the executive logging operation under the interview pattern.

Designated when another pattern of non-camera mode (or interview pattern), flow process withdraws from from program shown in Figure 13.

For more reduced data end position change editing operation, reconstruction of image operation can be omitted frame by frame.

Can from the edit menu that passes through predetermined operation calls, select the editing operation of ED position change, to change the ED position of desirable track.

But when when carrying out the data end position under the camera mode of logging mode or under the interview pattern and change editing operation, the user can be only reproduces operation and need not that present mode is become edit pattern and come editing data by carrying out.Therefore, the operability of video camera is improved concerning the user.

In addition, though the track as the target of ED position change editing operation can be selected freely, but when last track is the target of being edited, consider next picture that will take, the last track that is connected to this picture can be edited apace.Therefore, the operability of video camera is improved concerning the user.

In above-mentioned example, the structure that is used to change corresponding to the end address of suspending position Pst1 has been described.Perhaps, comprising the start address of using corresponding to the track of the address of the time-out position Pst1 appointment that suspends position Pst can be changed.In other words, the structure of the orbital data that is wiped free of before suspending position Pst can be implemented.

7. montage (Trimming) operation

According to present embodiment, the end address of track not only, and also its start address can be changed.

Therefore, when the start address of track was changed, its end address also can be changed with same processing.

For this reason, 2 of the data of reproduction positions are designated.Start address is changed corresponding to first appointed positions.The end address is changed corresponding to the back appointed positions.In other words, the data in the zone between 2 appointed positions are not wiped free of.Data in the zone between above-mentioned 2 positions are adjusted to new orbital data.

Next, with reference to Figure 14, will an example of this montage editing operation be described.

As shown in Figure 14 A, suppose that the reproduction of specific track #N is begun.As shown in Figure 14 A, the start address of track #N and end address are respectively A2 and A7.Reproduction is from start address A2.

When track #N was reproduced, the user can use specific key or similar equipment to specify 2 points.In Figure 14 A, carry out the primary importance assigned operation at Data Position corresponding to the address A3 of reference position A2.Therefore, some A is designated.

After an A was designated, track reproduced operation and proceeds.In this state, when the user carried out second place assigned operation, B was designated for point.In Figure 14 A, B is designated corresponding to address A5 for point.

After 2 some A-B were designated, when the user for example determined to use erase key 302 to carry out erase operations, as shown in Figure 14B, the start address of track #N became and some A corresponding address A4 from address A2.In addition, management information is rewritten and makes the end address become and some B corresponding address A5 from address A7.Therefore, as becoming the dead zone in the data field between address A2 and the A3 and as the data field between address A6 and A7 of orbital data after the A5 of address in the orbital data before the A4 of address.In other words, these data fields are treated as the zone of having wiped from the original track data.

In other words, when data were reproduced, 2 points were designated.After this, carry out the decision operation of deletion appointed area.Therefore, by this shirtsleeve operation, be used for the data of montage in the middle of original track and can be performed with the montage editing operation that produces new track.

Under reproduction mode, after the reproduction of the track #N-1 before address A1 finishes track #N,, and finish at address A5 in the reproduction of address A4 start address #N.After this, begin the reproduction of track #N+1 at address A8.

In montage editing operation shown in Figure 14, the zone between an A and some B can be by being adjusted as reproducing operation with reference to Figure 11 A to 11D and 12A described frame by frame (or by phoneme) subtly.In the montage editing operation, can select and edit any desirable track.Perhaps, as in above-mentioned ED position change editing operation, after having carried out the reproduction operation under camera mode or the interview pattern, can be to last track executive editor operation.

In the montage editing operation, can be in the zone between specified point A on a plurality of tracks and the some B, data are by successively reproducing from these a plurality of tracks.In this case, not at an A and some the data in the zone between the B by from being recorded in the data of all tracks on the dish, the editing operation of wiping (in the present embodiment, all track (all camera mode tracks or all interview pattern tracks) under identical pattern) can be performed.

Change in editing operation and the montage editing operation at above-mentioned Data Position, camera mode track and interview pattern track have been considered, moving image/sound be recorded/reproduce from/to the camera mode track, sound (as master data) and rest image (as auxiliary data) be recorded/reproduce from/to interview pattern track.Change in editing operation and the montage editing operation at Data Position, the audio track that only comprises sound can be edited.

In addition, the present invention also can be applied to the character information such as text data.For example, because sound identifying function and being improved so far, so the sound that is identified can convert the character information file to.

When Data Position according to the present invention changes editing operation and montage editing operation and is applied to this character information file, the check and correction operation of this document can easily be carried out.

According to present embodiment, the recording medium of disk shape is used as data by from this medium recording with to the medium of this media reproducing.Perhaps, present embodiment can be applied to the nonvolatile memory medium such as the very common flash memory that becomes.Nonvolatile memory medium is made of storage component part.In this storage medium, record data are managed with so-called FAT (file allocation table).When carrying out according to ED position change of the present invention editing operation and editing operation, the content of FAT is updated.

According to the present invention, ATRAC2 is used as the audio code corresponding to MD-DATA 2 forms.But, consider SoundRec operation to semiconductor memory, be not limited to this form.In other words, ATRAC3, MPEG1, audio layer 3 (MP3), AAC (decoding of MPEG2 Advanced Audio Coding), two VQ (transform domain weighting interlock vector quantization) or WMA (form medium audio frequency) can be used.

As mentioned above, according to the present invention, when data were reproduced, corresponding to the address of the stop position of shut-down operation (pausing operation), the end address or the start address of new data were designated.Corresponding to the end address or the start address of appointment, management information is updated.

In the equipment that uses tape-shaped medium's, data are recorded and do not contain management information on this tape-shaped medium's, and information should be wiped to this tape or from this tape by actual overwrite.But,, can be updated with management information corresponding to the end address of the stop position change of reproducing or the information of start address according to the present invention.In other words, need not to change data because management information is updated, the editing operation that changes end address or start address can easily be carried out.

In system, in order obtaining and above-mentioned end address changes the identical edited result of editing operation, data must to be cut apart, and one of data division of being cut apart to be wiped as the target of being edited with the data of management information managing recording medium.On the contrary, according to the present invention, this editing operation can be very easy to carry out by this way, promptly after the reproduction operation stops, carrying out data erase operation.

When wiping assigned operation and be performed, management information is updated in the structure of (that is, data are wiped free of), because user's the assigned operation of wiping is wiped free of data, can prevent that data from being wiped by mistake.

In the end address or start address can be recorded in data in the structure that is changed and edits under the logging mode of (camera mode/interview pattern), instant user has specified the logging mode of photographic images, and he or she also can executive editor's operation and need not to carry out the conversion operations that is transformed into edit pattern.Therefore, the operability of video camera is improved concerning the user.

According to the present invention,, select data the data on being recorded in dish corresponding to the record of current mode designated when a plurality of logging modes-for example, camera mode and interview pattern can be designated.In this case, because the corresponding selected data type of the logging mode of appointment, editor's operability is improved.

As the data of being edited, reproduced as the data of last program (track) management.When the actual use of user video camera, data are recorded in after the last program.Therefore, when user's editing program, be likely last program.Therefore, when the data of last track were reproduced, because it can be edited at an easy rate, editting function of the present invention became more useful.

In addition, after data reproduction stopped, when corresponding to the address (time-out position) of stop position in the time of can being changed, the data erase position can be adjusted subtly.Therefore, the user can obtain the more satisfied result of editing operation.

In addition, when corresponding to the address (time-out position) of the stop position of appointment afterwards or data division before when reproduced, the user can check whether the time-out position (being erasure location) of his appointment is suitable.

When data division was repeated to reproduce, the user can carefully check this erasure location.

In addition, according to the present invention, because 2 data positions of the data of reproducing are designated, so the reference position of data and end position can be changed and specify corresponding to these 2 data positions.In other words, when the regional designated data that are used to reproduce between 2 positions, adjust corresponding to the reference position and the zone between the end position of these 2 appointed positions and wipe before the zone of this adjustment and afterwards other the editing operation of data division can be performed.

In this case, this editing operation can be than the easier execution of situation of using tape-shaped medium's.In addition, need after carrying out the data cutting operation, not carry out the data edition operation of this complexity of data erase operation.
